Fig. 1. Some crossing EUV large-scale chains revealed by the modified TRACE image.

Some faint but very puzzling chains (or threads) are present on this image. At least three almost straight thin chains 1-2, 3-4, and 9-10 stretch through the solar disk from the east/south-east to north-west/west directions. Another thin thread 5-6 goes from the north-east to south/west sectors and are crossed with the chains 1-2, 3-4, 9-10 in points 7, 8, and 11.

Under attentive consideration, many other chains and threads can be seen on the solar disk as well.
